Hello Sofiko
Thank you for your designs. I think there is some potential for #119. I like the fact you have added an element of colour which helps catch the eye. I normally don't like orange but this works well, especially the way you have added a gradient.
I'm not quite sure what I would like to see but a couple of variants would be helpful if you have the time.
You might want to make the (&) orange or perhaps enclose the (&) with an orange circle using the same orange effect you used on the large (M).
Another idea is rather than have a separate motive, perhaps you can try a version which incorporates it directly into the name of the company and then make any additional changes to the rest of the font if you think its necessary.
I think the pools and spas needs to be a bit larger to help emphasis that this is a swimming pool construction company. At the moment, to my eye, it is promoting the city of Melbourne more so than the construction company.
The other logo although really good #118 is perhaps a little to syalised for my needs.
I hope this helps, and as mentioned earlier I do see potential but I think it needs tweaking. I will keep looking at it and get some other opinions.
Thank you again,
David
