Now this is what I call true ''Eye-candy.''. When I saw that you requested critiques for this wonderful art-piece,I thought that I could do one of them. But let me start with this interesting,sexy-looking Pony-Art.
Vision. The vision looks great.The background looks really well designed as well for Fluttershy herself.I love how you drew small white lines for her mane,which give it a little more detail.and the fainting blocks in the background also well done. Also,it's a nice touch that you can see a bit of her cutie mark under her dress.
Originality. Well,I find it very original of you that you gave Fluttershy such a cute and sexy dress and with a cute,fitting scarf It's so adorable and very original. It gives her a beautiful,yet carefully attitude.Only I saw already many Fluttershy's that was in the accept same position like this and was supposed to be a singer.Yet,you make it look very original and very amusing to look at it.
Technique. Well,I don't know much about Paint-programs,but whatever you used,it looks absolutely good.The colors you've chosen,the lines,the shapes. Pefecto mundo.
Impact. Alright,maybe the emotion wasn't as great as I expected,but that is just my opinion or maybe my fault. I don't know... But the impact that gave me when I saw this.I was just imagining that she was going to sing something for me.But hey,that is just my mind that is speaking. I think everyone has a different impact with this.I think Fluttershy could be an amazing singer and has a great talent with music or what-so-ever. The impact it gave me,was wonderful and I bet that feel will stay everytime I look at this picture.
