Dear Kamil, thank you for your design! We really like the concept very much: literally a house on a dune/beach. We would like to ask you to change the font as the second K in Kijkduinhuis is a bit hard to read. To make the distinction between dune and beach more visible, it might be an idea to look for more contrast between the two colours you used for the dune and beach.
One last suggestion (of which we are ourselves a bit doubtful): for non-Dutch speakers, the name of our company is hard to recognise. Maybe it would be an idea to make the dune and beach a bit more explicit.
thanks for your 'dot' design. We still prefer your first logo. Could you to change the font for this design as well, as the second K in Kijkduinhuis is a bit hard to read. To make the distinction between dune and beach more visible, it might be an idea to look for more contrast between the two colours you used for the dune and beach.
