Hello @gerglisofi17. I see you are new to Hive, so Welcome. First, I just took a look at your profile and didn't see where you published an Introductory article introducing yourself to all Hive members. I suggest you take the time to review the tag #introduceyourself or #intoduction and see how others completed their first post upon joining. Your post will help others find you. Check out the profile of: heyhaveyamet
Next, it's good that your friend recommended the LMAC contest. Did you get a chance to read the contest post first to make sure you followed all the directions so that your entry would qualify? This is extremely important if you want your entry counted as a valid one. Also, there is a wealth of information there that will help you complete your collages.
Take care.
