Looks good so far. The new wheels' angle is maybe a bit different than the original. A new background would be good. Arches aren't bad, but they might be a bit too wide. Cheers!
Nice ideas, the wheels look a bit too big for the arches tho, and a bit off perspective. The arches themselves also look a bit weird, like they're oval instead of round, the wide arch seems to stop in the same area as the original arch
