And There Was Drum Roll Chapter 1 part 4/4

Hello again I like how you are continuing with this! I agree with the comments made before me as well but I have some more of my own to add

He had got a tent of his own,

I think this sentence might sound better without 'got' in it

Brian was in his tent, beside a mattress, putting on iron-ring armor.

I agree with the comments Merlin made on this part, I would just additionally advise changing 'putting' as I think you could use a better word that describes the action a little more. Like 'struggling into' or 'heaving on' or something like that.

Rex looked nervous,

I think it would be more effective here to say how he looks nervous, describing some of the features that let Brian know he feels this way. Maybe he is shifting from one foot to the other or avoiding eye contact or fiddling with his hands? Anything like that would work

He held his bucket helmet onto his side with one hand.

I think 'against' might be better here than 'onto'.

The dab of the raindrops against the tent and the normal chattering of the soldiers outside

I'm not sure about 'dab' here to describe the sound of the raindrops, I think you could replace it with a more accurate word. Perhaps 'pitter patter' or 'pattering' or you could always describe more the action of the rain than the sound of it (if that makes sense ) for instance saying the 'onslaught of rain' or 'the raindrops lashing against the tent' or something like that. I'd maybe leave out 'normal' before 'chattering' here too, although that's just my preference

until Brian broke the backbreaking silence.

I'm not that keen on having both 'broke' and 'backbreaking', I'd replace one. Maybe 'broke' could be 'ended' or 'interrupted' or you could change 'backbreaking' to something like 'suffocating' or 'weighty'

Brian finished tying my sheath on.

I think 'my' should be 'his' here.

Rex’s face was covered by a shadow

Do you mean literally or figuratively? As you say later on that he does not look up I got the sense that he had looked down but I didn't know that from this. I think you could perhaps rephrase it a little to better show what you mean. Perhaps something like 'A shadow passed over Rex's face and he fixed his gaze on the floor' to show him looking down as well

he tried to look happy

Again like with the nervousness, I think you could describe this a bit more. Perhaps he manages a weak smile or something like that?

Rex lifted his hand in a salute that was all but too familiar by now

I'd maybe leave out 'but' here so the sentence flows a bit easier.

Overall: This part was quite short but I think you have done well in showing the loyalty with Brian and those following him, I hope you carry on

I think in general there are some areas that more description could be added to, I liked the little actions you had with each character and thought it worked well in setting the scene but when you are showing their expressions I think a bit more could be added. I pointed out the main two areas where I think this happens (where Rex is nervous and then trying to be happy), I think it would be a lot more effective to show the reader how they appear so You could always add a bit on how Rex looks too (as in hair colour and eye colour) so that the reader has a good image of him.

I'd also just think about waiting until you have written a bit more before posting as when it is written in quite short sections it's hard to connect them all together to get the bigger picture in what is going on I'm not saying they need to be really long, I'd just advise posting a bit longer parts.

Overall though I am still enjoying this! I'm getting more of a sense of Brian and look forward to reading more All my comments are just suggestions, hope I've helped!
