FromPerosnally I have quite an interest in changes caused by magical mishaps, so I was quite pleased to see this image appear. I think you did a very nice job in showing attributes from both characters together. I also like how you used the colors to make some slight alterations to show the fusion. It works out very well, where I can see both characters in this fusion. Pony designs in general are rather simple, but you used whatever you could very well to make your image clear; for example the new cutie-mark is a very nice little detail, just like the new hair style, which is a nice subtle combination.Now for the obvious point; I think it would've been interesting to show this image in a more full background, perhaps have some other characters around to react what they've just seen, even if it would just be Dazzle. The current filled background doesn't really take away from the image, but I think adding some more details in the background could add to the storytelling you're doing with the image.The character's expression is very clear and funny; and over the years you've nicely mastered your own style. The shading and lighting seems nicely consistent and make the image feel properly polished, while also not feeling overdone at the same time. In general I'd say that this is a nicely balanced image, showing off your skill in design. I think it'd be interesting to see this fusion in a few scenario's where the two previous personalities might be clashing somewhat. It could lead to some funny situations.As always, keep up the good work. The style you're working in is one you've mastered nicely, but try to keep pushing yourself in aspects such as the background or multiple character interactions. I'm not sure how much this is influenced by this being a commission, but for your own growth, definitely try to keep pushing yourself!
