Here's the vector I used for my Eyefinity Celestia wallpaper ([link]). Of course this isn't the same size (the original is 20,000 pixels wide). As with with anything I do, there's bound to be errors. Let me know if any are visible and I'll see about repairing them.
I thought I'd start releasing some of my old work sources since they're collecting bytes on my hard drives.

Use this for anything you wish. Don't worry about messaging me.
The crown is show accurate, which is good. You need to add details to the crown that are similar to the ones on the breastplate (the S shaped things).
You could try darkening the pink border on the tail (make it like dark purple) so it doesn't blend into the tail, and still turning down the white/light gradients on the extremes of the tail a bit. Where it folds in on itself it gets darker, not sure what software you used so it may not work but gradients can be used to accomplish this if they are angled. It looks like you mostly are just using linear gradients with 2 colors, you can add as many colors as you like and change the spacing between them, but it might be hard if your software doesn't let you angle them and blend them together.
