Not an expert but just a few things I would like to comment on:
1) As mentioned, the colors are very distracting, and the very strong red color in the background isn't the most pleasing to the eyes. Maybe you'd like to tone it down a little just so the red isn't too strong or too saturated?
2) It would look a bit more structured and clearer if you had a clear border separating the header from the main page from the footer. Right now they all have the same red background and it would be better if you could tell where they end and where the other begins.
3) Not sure if you've purposely designed it this way, but the number of ads in your webpage is pretty distracting for me. There are even some ads that feel like they aren't supposed to be placed in that way. For example, I saw one banner ad in between two items in the featured collections part of the page, and it was a vertical ad, that kind of messed up the spacing of the items, making the website look unstructured.
That's all I can comment for now! Best of luck to you!
