Last year, I made a low poly rickshaw model (9300 tris):
It has some flaws in both model and texture, and I'm planning to pimp it somehow for my portfolio. What are the most important improvements to consider?
Seems like you could do some work on the proportions, specifically the wheels, they look a tad too small. Secondly you could really work on your material definition. I'd retexture the entire thing personally!
Redo some parts you feel don't workout well, but in all honesty just do something new.
Going backwards isn't a good idea but if you think the piece is salvageable then re-work the textures and maps and first find what works and gives you the results your after.
Things I'd fix
-Weather it up, some damage to areas showing it's been around, those things aren't clean.
-Chipped paint were their is paint
-dirt on the tires as stated above, weather it up.
-details, such as head lights being lit, reflections, better cushion details, making the details bigger and using subtle cloth detailing that doesn't make you say what type of cushion is that.
-Maybe even the color scheme, those colorful lines are they in your reference?
-add a visible Wind shield, all nice and transparent, maybe a hint of blue.
-Also Texture resolution, find a target your current res looks small, or the Uv map is not optimized to retain better quality.
This is probably the best response you'll get a lot of people are too busy to comment now a days.
I'd also optimize the shit out of the tri count. That looks like it is a 3k tri vehicle, yet you spent 9.3k on it. Showing that you know how to make an optimize low poly object is still important.
