I like the way that this picture is made up of only the essential elements (hands, head, feet, that red-hot tongue), with everything else implied! The victim's distress in well indicated by the tight set of the clenched fists; the tickler's serene expression and rather dainty grasp suggest a confident, relaxed attitude. The color scheme is quite effective: plenty of warm pinks (nice that the two participants have slightly differning skintones); the central deepening glow well represents the pair's intense passion!
PS: Hi, Hungarian! Great to have you back!
