ND Filter on Flora

Went to Hort Park last weekend, wanted to try out the effects on ND filter. Woke up late and by the time I reach the park it was already 8 Plus. The park was crowded and there was a company event going on. I can't take scenery and therefore I fix my ND filter on my Macro 105mm instead. Didn't set up my tripod causes there was children running around. I hope I can reach the park before 7am in my next visit.
