I took 3D modeling at a community college on Blender a many years ago and 3D modeling in Maya Autodesk 2-3 years ago. I'm using Blender now because it is free and I like it better lol.. Relearning it as I go, but if you keep trying you'll be just as well.
The actual detail will go in before the characters are put into the game. Also, that background is not mine, just a thrown in background. Currently I'm adding this HUD to unity and moving a box around to see if it works.
