Senior Class Crest with colour

Photoshopped, and edited for quite a while. It's the last crest I made for my very last secondary school class... time flies so fast, it felt like yesterday when I just got into secondary school, and now, I'm gonna graduate this year !!! It's crazy.. anyway, this crest is probably the most meaningful logo yet to be made by me. the half golden bird wings resemble the guys in my class, whereas the half butterfly wings represent the girls. As I'm in pure science class, the water flow means the science stream.the growing roots and plants mean our knowledge that keeps expanding day by day. Finally, the big "S" has 2 meanings, Science or Senior... I'm gonna miss my class T.T
