These may be the best graphics! However, this is one-on-one tutoring with possible parent expressing relief. I also need to see your thoughts on red/burgandy and purple. I do like the blue and the green is shadded well. I like the feel as it says young but not chic. However, a little more distinction is needed. Maybe put a tie around the tutor.
I strongly encourage you or other to build. Create a defined parent (give this person a briefcase, cellphone, and or tending to youngster) and shade real light. Shade heavy on tutor (big presence with tie) and student (basketball/soccer ball at feet, but focused on work. I Like the Open Book and Pen out!! GREAT JOB.
Your message may really reasonate with one of my target audiences (my favorite) 4-8th grade Parents late thirties early -upper forties. However, the other demographic is mid-50s+ that prefers a touch of ivey (in the spring) or folliage (in the fall).
if you can submit one or both, you're really in the running.
will add the tie to tutor, will try to add a fourth person to ressemble parents and keep the two students and open book, will work on a couple of variations for you.
