Cut pound cake into 1-inch cubes. Reserve.

Place cottage cheese, ¼ cup sugar, and lemon juice in a food processor. Blend until smooth, about 45 seconds to 1 minute. Reserve.

Using an electric mixer, beat the 2 tablespoons of sugar and cream on high just until stiff peaks form, about 1 minute. Do not overbeat. Reserve.

Layer half of the cake cubes in a 3-quart serving bowl, then half the blueberries and strawberries.  Cover with all of the cottage cheese mixture. Repeat the layers of cake and berries.  Top with whipped cream and decorate with additional fruit, if desired.
