hmm you should never be pleased by current state of progress. It will stop you from enhancing to increase the looks of your designs as you're currently settled with the way it looks now. People can say it looks bad or good but this won't help you either. I tend to ignore these... as you WANT to get constructive critisim to fix your flaws. Tutorials can be helpfull in the start but reproducing a design is when you really start to make the world show thou art.
I hate how belimited I am with the budget on which I can spend for creating art. It also hold me back this way.
If I were to critise it even further is that these should be added or replaced:
Tires:
- spokes are sometimes going trough one another.
- no rim
Body:
- to fat and blocky, you should consider using more div's to ease inwards or to create more complicated shapes.
- you are missing a face at the back of the body (just above the rear lighting).
Overall use start to use references (or point to point & symetrical, though this consumes time like a sob)
+ front end seems abit on the lower side. might be due to perspective but i think it's the body that covers up the engine and stuff.
Owyeah I know that you didnt want a excact copy but the motor doesn't fit the title in my opinion.
e__e I might be a bitch about these things but when it comes to flames about art it will thrive the creator to do better.
