>>1244I could never draw on phones I think, if you have a PC you should try it there, I swear it's easier. Or if you have spare money you can buy a Surface Pro one day. They are as good as ipad pro but cost less and you can draw onto the tablet like a canvas. I think you can get the Surface Pro 6 for a few hundreds by now. I use a desktop PC and/or Surface Pro 7 though so I don't know how good 6 is but it shouldn't be very different.
ANYWAY, I don't have many tips. For me it helped that I always drew anime-styled stuff and that the IDW characters look like fancy mecha.
But in general what new artists should do way more often is: tracing for training.
Tracing is looked down on because people associate it with artists faking their proficiency. But tracing as training can help, I did it all the time when I was a little kid and it made me get a gist of how proper lines and proportions are drawn. You need to get a feeling for the bodies you want to draw, especially if they're huge like the ones Transformers have.
Also when you start drawing your own poses don't despair if the first sketch looks wrong or even if you notice 50% in that the pose looks off. I think it's normal to repose and redraw parts all the damn time especially with complex characters like TFs. Don't do outlines and details right away, I always make one VERY vague sketch first (basically just the dynamic it should have or the "shape"). Then a sketchy shape of the body like pic related. Then detailed lines which is where I do most of the changes by selecting and transforming bodyparts with the lasso tool and only after that do I start with the actual outlines kek
But maybe other TF fans have other methods. It also depends on the series too. Some series have twinkier designs so you can basically draw anime body types and add armor.
