I plan to join photo contests, need your advice fellow steemians

Soon I will be joining photo contests. Do you think these photos have the chance to win??? I wonder how it feels and what to prepare when joining photo contests.

We use Spike's camera most of the time, and he's the one who teaches us how to get the right angle and take  good shots. I wish I could have my own cam this 2018. Steem price is going higher so I feel I can get my own soon :)
