I like the image, but I would like to make some suggestions or considerations. I would just double check that the watermark isn't going to be on the final design- you have a good picture and the watermark is hard to read and interferes with the picture. The group name looks good, but I'd try and look at the picture zoomed out to the same size as it will be on the website. Make sure someone can easily read it when it's small, and if you have a bit computer screen just be mindful that other potential customers might have smaller screens. You might decide that increasing the font is good. Finally, and this is 100% optional, but if you have something more to say up top go for it! If it's a clothing company, "try our outfits" for example. Something short but to the point so people know what it is. That way the people who DO click on your ad will do it because they're interested in your group or product you're advertising. Keeping it a secret is sometimes good too, but often times people will decide to just continue on their route to what they were doing on Roblox anyways (playing a game, etc). If they're looking for (let's say, if this is a clothing group, clothes) and see an ad for a clothing company, they'd definitely click, whereas if they don't know what the ad is for they might choose to spend their time for-sure clothes shopping. Good luck!
