This is just my opinion, and I have never evaluated student portfolios for admission, but, this direction [fantasy sculpture] will not do you any good. I suggest developing your observation and artistic interpretation skills instead of naive visionarionism [ It is like vegetarianism [living without eating rich meat]. Visionarionism is architecture without logical basis]:
1: Draw natural things on sketch paper with soft graphite.
2: Dwell in and draw real architectural spaces with pleasant character, people, light and shadow on sketch paper with soft graphite.
3: See this book:

5: Buy these materials to get away from lined three-hole paper [It doesn't last - you will want to use paper that does not yellow and tools that make permanent marks. And keep everything. I still have a sketch I made in 1973 of my knee, crossed in jeans on a park bench. Took three hours with all that seam stitching.]:
