Doesn't look too busy, bit something else to consider. The picnic table, apron, burger master's arm, and lounging figure all point to the middle left of the image, where the trees are...The fact that the trees are highlighted and also pointing in this same direction (kind of a 45 degree slant, rt to left)...all this serves to draw your eye right off the page, where the trees are...maybe toning down the lights on the distant trees, or counterbalancing the vectors which all point this same direction (by strengthening the perpendicular vector along front of the grill, or maybe even opening the grill)...this may serve to keep your eye in the painting...
