Necesito Ayuda........HEEELLPP!!

Okay so Ads....umm. I need suggestions. I have some ideas on what I want to do, but I'm having a problem translating them to the computer I feel like everything that I've done looks really.....I hate to say amateur, but that's the only word I can think of.  I am not sure whether to illustrate them which is what I'm interested in, but the way I've illustrated them up to this point is to draw them straight into illustrator using the pencil and pen tool. Does anyone have a better idea or way for me to try? Also my first thought was to use photography, but I am not sure if I'll be able to take pictures of what I want to communicate with my ads. I'll post what I have so far and I'm taking any opinions and suggestions!
