Hey Ross, I have some suggestions for your drawings that I think will help you. I took some of your drawings and drew over them to show you what I thought you could do. Mostly it has to do with gesture because you tend to use a lot of straight lines, causing your drawings to be a little stiff. I hope you find some value in these and they help. Keep drawing :)

in my perspective the chest should be more squashed down over his ribs just a bit and his chest should jet out a bit more that's it. i love this though. and i already love war hammer art its so awesome and i think that this is no acceptation 👌😁 so good i hope that your friend really likes it and i love wear your going with this keep up the awesome! work! 😉✌

I have some friends who are really into 40k, I've only played a game or two. But I think the oversized shoulder armor, skull decal, etc. definitely says warhammer! You could look up Karl Kopinski for some rad 40k inspiration as well :)
