Just flinished this pilot helmet within C4D, with a UV mapped basic Texture. Later on this will go along with my vest - Mesh Review and Feedback. [Polygon count 10,900] Helmet 10,000. Glass Visor - 900 (In the future this will be reduced to make it one object)
Wow, looks good! It looks like I’d take’d some time, keep It up 
Looks great, but add some more colors/detail, anyways great job keep it up.
The final work looks good, but the smoothing and topology are awful. I suggest not using a subdivision surface for game assets, you can try to redo this mesh but with a better topology; What is a good topology? Brief summary: It is a mesh composed only of squares or triangles in an organized and optimized form without ngons, there is no need for so many faces for a simple mesh like this, you can search more about on Youtube or DevForum.
Most of my meshes are designed to go in short films, or edits. And for this I push the polygon and detail way above the normal roblox intake. This being said when it comes to import into roblox I go simply ploygon formations with a very low polygon count to inport it in.
Yes, I mentioned about that. Even so, you need to train topology.
