Great job!
One idea: Have some tracks ( from Spotify api?) to play along that matches the selected scales.
I've found that playing on top of songs works pretty well, improvising up and down is very easy if you are playing the safe notes of the scale, finding how the singing melody fits the scale, then how the solo fits the scale..etc is a funnier way to memorise the scale.
I've found a looper pedal a fantastic tool for learning theory. Play some chords from a particular scale, then try improvising over it. You get a real feel for how the different modes sound.
