An amazing piece of artwork, i especially like how you have created the background too. The hair and roses are in fact the best!!!! As this is a critique, you want some advice no... here it is... your body needs a little working on-thinner-,her face could be a little more straight-point ie chin-. Then your mistakes could be adjusted)there is one on the t-shirt. There is nothing else to say but this piece has lots of originality and flare, your background holds alot of impact(use this type of background more in your work).The picture is well... outstanding in my perspective 10/10 well done on this piece of work.
I would like to state first is that this is my first critique. So please bare with me and I do hope what I am saying is accurate and does make sense. Second, I shall be basing your image off of this one: [link] but at the same time giving off my personal opinions as well. I'll try not to be too harsh when it comes to comparisons. Ready? Lets begin.
I really like the background as it makes the character "pop" out to the viewer. Also, I like how you drew the flowers. Very nice and seems very accurate to me, comparing with the actual image. The "lighting" seems well done as the shadows does give the image a 3-dimensional feeling. In addition to that, the shadows are well put in considering the type of background you provided. So not too much and not too little; just right.
Now time for the blunt and brutal but helpful part of the critique. The chin seems very disfigured to me. It should be a lot sharper and smoother. The body needs a little more work. Comparing with the actual image, she needs to be skinnier. As for her hair, it seems flat, as in, it doesn't seem natural. I would advise you to try to make her hair more smoother and give it more of a flow. The hair just seems to be hanging or dangling there. So again, the hair needs to look more "flowy" (not sure if that's a word lol). And finally, and be warned that this will seem very brutal but, I would consider using guidelines, especially for the anatomy. I know guidelines are annoying and most people would just want to get right into the drawing. But without it, there won't be much consistency when it comes to future works. Again, sorry if that sounded brutal but I have to be honest, especially on a critique. If you ARE using guidelines, then I would advise you to practice on using guidelines as often as you can. I can assure you that with better guidelines it WILL benefit you in the later future.
Overall, this is a beautiful masterpiece, a very well attempted one. You really have a lot of potential and I encourage you to keep working on what you are doing. Sorry if the guideline part sounded brutal but, like my professors have told me, I would never cheat you when it comes to making you better. That's what's important. Anyways, nice work!
