Generally good.
Seems quite basic on the audio-side with very few samples covering the RPM range, were these recorded from the real car? There is minimal depth and detail to the lights, front or back, with no tail lights or flashing headlights activation, no texturing anywhere on the rear suspension and transmission section, and generally a lot of colour banding and low quality on textures that could have been exported at slightly higher resolution and some high resolution texture maps could have been applied even for the car brand logo.
LODs are generated using CM tool rather than at least LOD B done by hand, and the red stripes on the first livery are not cut in 3D; being painted in freehand meaning it has less precision in its application. You can identify this at the very front of the car floor where the lines do not match at the bump, or the leading and trailing edges of the side car floor. This also leads to bolts inside wheel nuts or fuel filler caps just being simple textures.
There is not enough smoothing applied to some prominently visible objects nor standard smoothing practices such as fake-chamfered edges applied to reflect lighting properly. Some example of hard edges or inadequate smoothing areas include tow hooks, dive planes, wing end plates, leading edge of the car floor side, and more. There are also some jittery parts fused together more visibly seen between seams on the sides of the car (seams and gaps north and south of the letter 'C').
Physics and feel is generally up to the driver and best efforts were provided to get the job done with the information provided.
Overall, this is generally a good vehicle and does fit the free project category fine. Having spoken to Radical regarding this project in the past, it seems their objectives have changed in terms of specification; no particular fault with the dev team.
