Nothing wrong with your axes as long as you have a good set-up and they feel good to you and you get the sounds you want.
I think your next axe would come after trying anything you can.. Any freind, teacher, any music shop that lets you try one, which I guess most do these days. Also try them with the type of amp you have or are going to get in the future.
You may want to post your desired genre, you might get some good comments about what works best.
Try rigrundown for your favorite player..
here's an example
