|At your age, there is a lot of competition on dating sites. You should consider dating in real life.|
The children are not mine (niece and nephew) but I thought that for some women seeing a man with kids was a positive.
You are not the first person to think this way, but it is not correct. At 22, you would be perceived as having baggage, with two different children in your photos/life.
Most people will only view your main image, and instantly move on (without reading the profile), when they see/assume you are encumbered by children, at 22. They figure you have many resource commitments, including time and money.
Still don't understand why folks don't realize the main photo is all important.
My advice: REMOVE any photos with children from your profile (did you get permission of your sibling to post them here? Doubt it.).
Get a full body pic posted. If you have teeth, try to show some of them. Can you seem a little more animated? Your pics look like the same pose, with a different background slid behind you. You need to look a bit more "lively" at your age.
Somehow, I don't think you will follow this advice, but the kid pics are a show stopper, and not in a good way.
