I’ve wanted to be in the UGC developer program for a while, but I have no idea how to get in or what their requirements are. I have been modeling several objects in pixel style and I would like to know your opinion and give me advice because I am thinking of seeking help from a ugc developer to be able to upload this accessory to my group. 
Wait for them to open UGC survey. Some people got there just by posting their creations on Twitter (now X…) .
Is your username " WILAN " by any chance?
The model you showed looks good. You have to submit a UGC Application to Roblox (search it up here on the Roblox Developer Forum), and then wait a few weeks/months. In the meantime, you should get better at modeling and practice and learn every day. If you want to, you can also post your models and creations on other social media to gain attention.
