Hello all! I decided to start a new project, focused on 3dn-ifying Gradius! Using Dippy0615's 3dn file as a base, along with JJXB's UI code, I am making adjustments to make this similar to the style of my Metroid project. I have decided to name the series 'Defined' after just coming up with the name while I was lying in bed one morning. Anyway, here is an early look at what I have done so far! (Although I only started it a few hours ago, so bear with me.)
Honestly, the title screen is about how far I have gotten so far, which just had different layers similar to the Metroid one. Here is a comparison to the standard NES, although they are not too different, honestly.
However, when comparing the ship, you may notice that it is layered as well, and when comparing the two, it doesn't look too different from head on...
See? Not that different at all! However, when looked at from a different angle is where my real work shows, I believe!
As you can see here, I have not just added different layers, I have actually used the layering system to make an entire 3D model of the Vic Viper. (With standard and retina variants as a comparison.) This is what I have put most of my time into, and plan to do this with most entities in the game.
The ship itself is based on Gradius' box art, and other concept art of the ship itself. 
Here is some of the art I used as a reference, although I gave it some personal touches as well. I'm rather happy with the results, although this does mean that this could take some time... Now I have to go work on the other Sprites for the ship. Let me know what you think of it, and let me know if you think any improvements could be made! I'm looking forward to seeing what the final product will look like-
