did I text her too romantic/intense?

I have a met a girl and we had a great date together. we planed to meet each other next week because this week she was busy, meanwhile i texted her once to let the spark be alive, she replied positively and 2 days ago I texted her "Hey, I saw you playing in the sky", and then I draw some birds and one angle in between. So, I think maybe its too much, but on the other hand, I use this kinda pickup line(I make them) and she always laughs at them, and says they are surprising! but I dont want her to be overwhelmed, because we only have met once. So, since its 3 days and no reply, did I screwed up or she is busy?(she read my message today morning in WhatsApp)
