Hey saffysparkles!
Nice portfolio you got there. I have never heard of an engineering and some other art double major, but I think that may be tad too difficult. Both majors have long hours, and getting a schedule to fit may be too hard for you to balance and succeed. I'd think about what your career goals are. Do you simply enjoy art as a hobby? Then maybe majoring in engineering and minoring in art is for you. But I reckon such a feat is possible. It probably also has a lot to do with what program or school you choose. For example, RISD/Brown Dual Degree might make it easier to do such a thing than another school. But I would call up the admissions counselors of schools you are interested in and tell them your career goals and what you are considering majoring in. They will be able to give a good idea about what is academically possible. Don't let my words or others deter you though. At USC when I asked about doing their Thematic Option program and being an animation major some faculty told me that it was not very possible. But I met a girl there who was doing exactly that. Aim high!
Now on your portfolio, what strikes me first is that you have a lot of pieces. Probably more than you need. And I would suggest taking some out because some works are stronger than others. If I was you I would take out:
The Prices: I can see having them on for your personal website but I would consider taking them out for colleges
Paintings: Kettle Still Life and Water Carrier
Wet Media: Emanata from the Library, The Death of Man, and Sophie’s Swing .
Dry Media: Birds, Underwater Mysteries, Hope is a Thing with Feathers, Queen of Hearts, and Ink Eater.
Digital: Books Take You Places (or at least get rid of the font on top) and The Last Hour
And on your about page please use capitalization to properly write down your awards. Please also separate your awards from your schooling (aka Tyler pre-college)
I’m assuming you are a junior so while you have most of your portfolio done, you will have time to make more work senior year. I would also try to work on color. Your colored work is rather flat. Try to find the different colors in colors. Nothing is simply yellow or blue. If you practice seeing the colors within objects or look at some masterwork, this will come easier.
Fractured Reflection seems to be your strongest piece and your best work is your most current (i.e. 2012) Take the rest of the stuff out and your portfolio is definitely competitive. Don't forget to go to NPD. I'm sure you'll meet some interested admissions officers with praise and pointers. I do not know what major you are interested in art wise, but if it is illustration a few more conceptual pieces would be nice, especially if they are in color. And add in some sketchbook pieces. A lot of schools love to see students develop both ideas and compositions. And if something is in a series reference that in the additional notes section on each piece (i.e. "The Meeting", Lovers in Paris. ) If you add more strong pieces take the weaker ones out quality over quantity is your best bet. Good Luck!
