This is a really beautiful image, as a whole. A lot of effort when into making this a reality, from posing hi-res 3D models and organizing HUD.
The battle scene itself is very original. Simple things such as Link holding a new weapon and Kirby's confused facial expression show that there's something new to the table. The design of the Final Destination is very simple, but that doesn't mean it's bad at all.
The only thing that I could complain about is lighting. It's done very well and I LOVE that its colorful, but there's something about the lighting I can't put my finger on that looks off.
Either way, good job! It's an impressive image and I would love to see more like it.
