well i dont how to draw and i dont know how to colour either XD

Your gallery has a colored work of a sword equipped pooch, and a bunch of other sketches. Your outlines are solid and there's always likable characteristic expressions. I think you can do a lot as it is, and also as your gallery shows.
However, the only thing I think all of your working actually asks for is a sense for order. It can be in just doing the pictures themselves, making attempts towards applying composition. There's also methodology - drawing things singularly but apart from eachother. Designing is a great concept and a really good strength, but usually in task it develops mostly particular things as stand-alone: Self contained ideas. Composition affords the opportunity for things to find their order, where each singular pictural thing fills the need of another. It sounds different or a bit weird maybe if you haven't heard it that way.
It isn't that while you're working there's negative and positive things in practice. It's while you're working at your strengths, there's inherently from that a positive need.
So the approach is important. You might merely aim to improve in making a better looking picture, but then there is still that inherent need to be addressed. Otherwise, what has constituted as the expression in your art?
Great gallery, and great work.

what he said! too many doosles, not enough finished pieces!
