Very good, the squared paper will help you with perspective using the computer digitally will help with colour and tone. Try watercolour not painting up to the lines like a colouring book, but a wash (Watery paint applied to a wet area) leave dry, then draw on to it and paint again. It is a great! way of painting.

Oh thanks for all of those advices Braifree ! But it's made with my black pen generally in class... That would be a bit difficult to take all of this material with me !!! LOL Thanks Again !

Well! wherever you draw Keep Drawing. Just trying to shown an interest. A quick sketch is great but should be followed later.

Yeah you're right.
