Illustrator A1 Alphabet

This was the first time i had actually sat down and used illustrator, it was a whole new program i had to learn. I thought compared to photoshop it was hard to get used to because of the locking of the layers, and how to save to document correctly. I picked up on quite a few other tips, like what document i need to use for a certain item. I think now that i should be able to use the program but there are parts that i would be unsure on but if i don't know how to do something i would just ask for help. My final A1 sheet wasn't to visually exciting but i am happy to look at it for progress.
