OC- Spinel and Casino

A certainly captivating artwork.
I see a lot of originality in piece and the execution is splendid.

The character is sweet, the design is nice and I like how it resembles a bunny. I also happen to have a soft spot for pink haired girls, not because it's a "feminine" colour but because I think it fits the generally sweet nature of the females. A little stronger shading at some parts of the hair to show more depth perhaps would have added to the picture as well as more shades of purple similarly to the middle part of her hair. Some subtile highlights of purple may have enhanced the drawing as a whole and add a more fantasy-like atmosphere. You could try it in future drawings.

The eyes seem to be a little out of place in comparison to the rest of the drawing, as if they are following a different colouring technique. Although this is partially the fault of being too small, naturally when a piece focuses on other things but I also don't have any information about this character and therefore I don't quite know if the eyes are meant to be that way, so my apologies there. To be more clear, what I see in the eyes is quite old school shoujo-genre style while the rest of the piece seems leaning to towards the more modern anime colouring. I hope I don't seem to persistent to the eyes but I simply consider eyes very important on a character.

The little details and the overall composition is stunning. I can see that you have clearly put a lot of effort into this artwork and you didn't neglect small details, even the cards are well coloured and shaded. I should mention here that the colour choice is very good, the colours are in harmony.

My concern is the way her outfit was drawn. There are some parts that are out of perspective but I don't blame you, the outfit seems rather complex and hard to draw. This is merely a hint as to what you may pay attention in the future.

Last but not least, I'm happy that you chose a simple background with dark tones. It really brings out the best out of the two characters, it creates perfect harmony and atmosphere. The little sparkles and stars were a great addition, too.
