After looking at your stats I think you are playing way too passively. For 6max a 24VPIP isnt bad by any means, but you need to be raising more than 7% of your hands PF to help balance that.

Your Stealing % is also very low, something near 30% is what I would shoot for, and will definitely make a noticeable impact on your winrate.

The biggest thing I noticed is that you WtSD is waaaay too low, giving you a very high W$SD, you are folding too many best hands. I think this also has an impact on your aggression stats. Preflop you are very passive playing a lot of hands and not raising much giving you a low aggression factor. Since you are folding so often on the flop you are really only continuing with the best hands which you are aggressive with so your AF will be higher on the later streets. This is going to make you incredibly readable, if you show aggression, you have a hand. At $25nl this wont matter a ton, but as you move up it will.

The other big thing I noticed was in your position stats image. You are raising less on the button than any other position except the blinds, you dont seem to be adjusting much for position at all which is something you need to do.

I think you can win playing this game, but I think your winrate will drop from what it is now and as you move up you will need to make these changes. So while this will beat $25nl for a decent amount, you should really be working on fixing these things to develop a solid game to work with that will beat the levels as you move up.
