What beautiful examples you show us @silviadiez, it really is a pleasure to observe the simplicity of the message expressed with a charming chromatic harmony and a great example in the composition. I look forward to seeing great work inspired by your examples, I also look forward to seeing how the level of participation opts for quality over quantity, which in the end will give prestige to the contests, no doubt benefiting those who have real respect and appreciation for the Visual Arts.
I wish the best of luck to the participants and I'll be very pleased to see their work.
