Nah mate, they're decent. I'd say keep doing that stuff, straight letters. Maybe a bit on bars. There's a few so I'm not going to go into The individual pieces
Thanks, I don't know why but I struggle with shadowing. It looks OK when I sketch it but comes out awful when I put color to it for some reason
U should do 3D object studies, even just basic studies and not just letters but abstract shapes makes it easier to add 3d to even the wildest styles
