No, don't ever say your poems are clumsy or silly, because they are neither and a blind man could see they come from a thoughtful and inquiring mind. I believe that it doesn't matter how people write, what form of rhyme they may or may not use, its
WHAT they write and the emotional response they can elicit from us when we read their words. That's what really counts and means something. English is not your native tongue, so that makes your work all the more to be admired, because you think all these things in your mind, in your own language and then put them to paper in English. You do a real good job mate.
Now Sergo, I will get down off my soapbox and shut up.

By the way, if you don't understand 'get off my soap box' it's something like this. There were times when people would get up and speak in public about issues that meant a great deal to them personally. They often met in parks and such like and they would get up on an old wooden box, (the type they packed soap in for delivery to shops) and they would speak to the passing people about whatever they felt strongly about. SO we use the term, of 'getting on our soapbox' when we talk at length about something we feel strongly about. Does that make sense

Hope so. Keep writing Sergo, good on yer mate.
