Looks ok, you need to sort out the roof and back wheel. When you use markers you need to use long smooth hand strokes. Also, the front air intake by the front wheel is alot bigger than the rear wheel, which makes the rear one look a bit wierd. Good for a first try though! I'm sure AnsisK will write a book full of information to help you improve!
j/k.
