First off, let me start by saying that I love the work that you've done in all of your designs, from the monthly dresses to the website-based gowns. I even enjoyed the designs based on the hair color, and I imagine this to be no different.
However, there are some drawbacks to this piece, nothing too major. Looking at this piece, I can see that you have steam (which can be caused by boiling water or another form of evaporation), but not mist.
Most would argue that mist and steam are the same thing when they aren't. Mist usually lingers over warmer water, when cold air makes contact with it.
And since I see that there are multiple designs for liquid form (and a couple for solid form), I feel as though mist deserves a spot in your design sheet as well.
Other than that, it has a great impact and the idea is quite original (as are a lot of your works), the technique is brilliant (I imagine that, since you said that this was a school project, it was mandatory pencil sketch), but the lack of a mist design makes me rate the vision at 4.5 instead of a perfect 5.
All in all, I look forward to seeing more work from you in the future. Here's hoping for many more great designs.
