Hi, stttNNN
Oh! Good to see you got Equilab!
Whether it is too tight or not is SO dependant on your post-flop skills.
If you are good post flop, you can open wider, if you're still learning, it is OK to be somewhat tighter.
When you are looking at the hand range window, on the right hand side are some "predefined hand ranges". If you select they type you want, you can click on the position to see what the "standard" range is.
The range you show in your post matches the short handed MP standard range almost exactly. You have added QJo and QJs -- not much of a change.
You don't say what limits, and what type of game you play.
At lower limit zoom for example, people play very tight, so wider can be OK, if you can remember to fold when necessary.
You might also want to watch a coaching session for the type of game you play, and ask your coach what his standard range is.
Best of luck,
