Can you upload a higher (bigger) version of your logo?

sure

there's really one 1 design that's even in contention - most of the designs simply use my original idea with some different images, they're certainly not worth the money I'm paying. I'd really like to see some originality!

any feedback on the newer entries?

I'm just going through to make a decision now. one thing I note is the mention of my having to purchase images - that won't be happening.

when I produce commercial work for a client I might include stock footage in a draft but I would never ask the client to pay for it - seems extremely unprofessional to me.
