Steve you're great. Love the enthusiasm here. Ya need work though homeboy. Lot of it. The first thing that immediately bugged me was how James was drawn with filled in click-and-drag shapes. Broham draw your best damn circle no matter how bad it looks, the consistency in style will help a ton going forward. Second thing I want to highlight is the mouths. Move em forward. Having someone talk out their jawline looks straight up off-putting.
Truth be told a lot of what you could improve on will just come with time if you keep at this sort of thing. A big thing I'd recommend is using a smaller brush size for your outlines. It'll give you more room for the faces and clothes to breathe a little.
Your intro & credits should also be heavily cut down, doesn't add a terrifying amount right now. Regardless of all this I took note of the black and white sections that were actually really well done. Sketchy af, but really stark in terms of quality compared to the rest of the schtick.
Keep doing what you're doing, and recognize that you're still chilling with the bottom boyos right now. Don't stop drawing and keep trying to do better, don't wallow in the same stuff you're used to. I believe in you SteveTheRapper. Row Row, fight the power.
