Looking good. Are you drawing with a graphic tablet. Or are you drawing directly on the screen of a tablet. If you implement line weight into your drawings, this will improve the look greatly. You can watch this video by Jazza to understand what I mean.
I draw directly on the screen of a tablet. I'm leaening how to do shadows and gradients of colours. I have seen many video of Jazza😊 Thank you very much for the advises, they're precious 😊😊😊
