For starters, your figures look great. The problem may lie in the transfer directly from phone to on-line. Sometimes formats get compressed or altered in some way; I'm no expert, I have my kids handle the technical side of things but I'm using a Samsung S-9 and it takes pretty good picture even in the fluorescent light in my game-room. Hopefully there is somebody with some tech-savvy that can help.
It would help to identify the type of phone that you are using.
