Have you tried looking at some youtube or google tutorials? Or maybe loan a book from a library? Wish I could give some advice for fur... I don't think you'll have much trouble learning as your basic outlines and proportions are good :)
If it's a close up work I'll do every hair. Takes time, but looks more real. I've just done a cat recently, and have drawn the hairs and have started blending them with strokes. I'll get it up on my thread soon. It was HARD to say the least! And I still don't know if Im satisfied with it. Lol
Suede board helps achieve the fur look but you have to build layer upon layer to get fur to look realistic.....in other words...it is going to take a lot of time. Confuscious' cat has wonderful fur. Unfortunately I can not see your pictures on here. I can see Confuscious' drawings tho.
